Are you encountering the 'com.example' restricted error while developing an Android app in Android Studio? This error occurs when you use the default package name 'com.example' in your app. In this guide, we will show you how to change the package name in Android Studio to resolve this error.
Why Change the Package Name?
The package name is a unique identifier for your app. It is used by the Google Play Store to identify your app and differentiate it from other apps. The default package name 'com.example' is used by many developers as a placeholder, but it can cause conflicts with other apps that use the same package name. Changing the package name to something unique will prevent these conflicts and ensure that your app is easily identifiable.
